| Popis: | Up to 15s H-mode plasmas with 8MW of ICRH power were executed on JET, with the JET record high injected ICRH energy of 108MJ. The ICRH discharges, using the H minority heating scheme at 3% minority concentration, were stationary without any major MHD activities or impurity accumulation. NBI heated discharges were executed consecutively to match the dimensionless plasma profiles of q, ?*, ?*, ?n and Ti/Te using the same shape. Both pulses had gas puff modulation at 3Hz for the whole duration of the discharges to extract perturbative particle transport coefficients. The ELM frequencies are 75Hz and 45Hz for the ICRH and NBI pulses, respectively, with mixed ELMs and affected by gas puff modulation. |
